Manual setup

  1. Copy Drivers\SGL2.dll into your classic Quake II folder, beside the installed quake2.exe.
  2. Open Command Prompt in that Quake II folder and run:
"C:\path\to\RenditionLauncher\Engine\quake2.exe" +set vid_ref gl +set gl_driver SGL2.dll

Replace C:\path\to\RenditionLauncher with the folder you extracted. For the original driver, copy Drivers\SGL.dll instead and use SGL.dll in the command.
